Custom Precision Slotted Spacers Stainless Steel Brass Aluminum Sleeve for Industrial Use

Description

What are Slotted Spacers?

Slotted spacers are specialized fastening components with slots or grooves that allow for adjustable positioning. They are used to maintain precise gaps between parts, absorb vibrations, and provide structural support in assemblies where alignment flexibility is required.

Materials

Slotted spacers are made from various materials, depending on their application requirements:

• Stainless Steel (AISI 304, 316) – Corrosion-resistant, high strength

• Aluminum (6061, 7075) – Lightweight, good conductivity

• Brass – Anti-corrosive, electrical conductivity

• Plastic (Nylon, POM, PTFE) – Insulating, lightweight, chemical-resistant

Surface Treatments

To enhance durability and performance, slotted spacer may undergo:

• Anodizing (for aluminum) – Improves corrosion resistance

• Zinc Plating – Prevents rust on steel spacers

• Passivation (for stainless steel) – Enhances corrosion resistance

• Powder Coating – Provides additional protection and color coding

Specifications

Slotted spacers come in various sizes and configurations:

• Inner Diameter (ID): 2mm to 20mm (or custom)

• Outer Diameter (OD): 4mm to 30mm (or custom)

• Length: 5mm to 100mm (adjustable)

• Slot Width: Typically 1mm to 5mm

Applications

✔ Électronique – PCB mounting, heat dissipation
✔ Automobile – Vibration damping, engine components
✔ Aerospace – Lightweight structural support
✔ Machinery – Alignment in mechanical assemblies
✔ Renewable Energy – Solar panel mounting systems

Excellent Case: Adjustable Solar Panel Mounting

Industry: Renewable Energy
Challenge: Solar panels require precise spacing for thermal expansion and airflow to prevent overheating.
Solution: Engineers used aluminum slotted spacers (anodized for weather resistance) to allow adjustable panel positioning while maintaining structural integrity. The slots enabled fine-tuning of panel alignment without requiring custom brackets.
Result: Improved heat dissipation, reduced warping, and faster installation with flexibility for future adjustments.
